Patent CA-2112762-C (CA)

Abstract: Portable stations with a single receiver can perform communication using a plurality of slots in one frame in time division multiple access (TDMA) transmission.  When communication is performed between one of the portable stations and a cell station with data of two 32 kbps data into which an exchange converts one 64 kbps data, the portable station occupies two slots in one TDMA frame.  A controller of the cell station assigns these two slots as being separated from each other by at least one slot.          Alternatively, the controller assigns these two slots as being adjacent to each other and assigns same carrier frequency to these slots.  Thus, communication with a transmission rate of 63 kbps can be performd by using two slots or two channels of 32 kbps.

Abstract: A telescoping draft link assembly includes a hollow first tractor-coupled link and a second implement-coupled link slidably received by a channel in the first link.  A pocket is formed in the first link next to the channel.  A plate is pivotally mounted in the pocket and is pivotal from a release position wherein the plate is entirely received in the pocket to a locking position wherein at least a portion of the plate projects into the channel.  The second link has a notch formed therein, an end of the notch forming a shoulder which is engageable with the plate to releasably hold the second link in the retracted position.  A spring is biased to urge the plate towards its locking position and a knob is attached to the plate so that an operator may pivot the plate to a release position.

Title: Transcription interface for a word processing station
Inventor: BENTON RICHARD COY JR
IPC: G10L15/22
Filed: 1994-03-08
Granted: 1999-04-20
Abstract: A transcription interface (10), connected to a general purpose digital computer ( 11 ) and a digital dictation recorder (20), for controlling various transcription functions and for automatically transferring information concerning dictation from the recorder (20) to an application program running on the digital computer (11). The recorder (20) generates a sequence of digitized dictation signals including a dictation segment and a digitized identification signal containing information corresponding to the dictation segment. The transcription interface (10) supplies an audio signal to an audio port (43) by converting the digital dictation signal to a signal that audibly reproduces the dictation for transcribing by a transcriptionist. The transcription interface (10) also formats the digitized identification signal to generate a message signal having a signal format compatible with the interface (10). In response to an interrupt signal generated by a timer interrupt circuit (17) of the computer (11), the transcription interface (10) automatically sends the message signal to an application program running on the computer (11) for display by a video display (14) connected to the computer (11). In response to an interrupt signal generated by the application program, the transcription interface (10) supplies a status signal containing information concerning the operation of the application program to the recorder (20). The operation of certain keys on a keyboard (13) connected to the computer (11) generates keyboard interrupts that initiate various transcription control functions by the transcription interface (10).

Title: Speech coding system
Inventor: MIYANO TOSHIKI
IPC: H03M7/00
Filed: 1994-03-14
Granted: 1998-09-22
Abstract: An adaptive codebook having an excitation signal predetermined in the past, an excitation codebook for vector quantizing an excitation signal or the input speech signal,and a gain codebook for vector quantizing gains of the adaptive and excitation codebooks are provided.  A perceptually-weighted speech signal having a subframe length obtained by dividing the frame is developed by using the input speech signal and the spectral parameters.  A zero input signal of a synthesis filter is developed for a predetermined length by providing the input speech signal of the present subframe as an initial value to the synthesis filter on the basis of the spectral parameters.  An overlap signal is also developed by weighting the zero input signal on the basis of the spectral paremeters;  Optimal codevectors are searched from the adaptive, excitation and gain codebooks acoording to a signal obtained by connecting the overlap signal to the trailing end of the perceptually-weighted speech signal.

Abstract: A glazing assembly is described, suitable for use as an emergency escape, comprising a laminated panel having at least two sheets (10, 12) of vitreous material adhered to a polymeric intervening layer (14) which extends continuously between said sheets (10, 12). In at least one minor area zone of the panel, the possibility of elongation of the intervening layer (14) under the influence of mechanical stress when said at least two sheets (10, 12) of vitreous material are broken, is different compared with the possibility of elongation of said intervening layer (14) over the rest of the panel. The assembly may be used in vehicles, such as in high-speed train carriages. When there is a need to break through the panel for emergency escape purposes, the panel is subjected to a suitable mechanical force, the intervening material (14) is more easily torn or cut away, thereby enabling faster escape. The invention thereby enables easy escape through a window space while maintaining the security performance of the assembly at a satisfactory level.

Abstract: The disclosed fish landing net includes a telescoping handle movable with respect to two handle-engaging "mirror image" lock pieces, each of which has a pair of interior grooves. When the net is in use or when the handle is being telescoped toward the distal portion, each groove of each lock piece is in registry with the corresponding groove of the other lock piece. Axial ridges on the handle engage respective pairs of grooves and prevent relative rotating movement between the handle and the lock pieces. A release portion at the outer end of the handle permits the lock pieces to be rotated with respect to such handle when the net is being folded or unfolded. The net also includes a locking member preventing telescoping handle movement when the net is erected ready for use.
